3 Claims.

This invention relates to bun pressing maz chines.

An object of this invention is to provide afmachine whereby bunsdisposed in a baking panrmay be compressed to the desired degree.

Another object of this invention is to provide a machine of this kindwhich is provided with an oscillating pressing means r.adapted in oneposition thereof to engage a flour receptacleor holder, and in anotherposition thereof to `press down on buns which are placed in a bakingpan.

A further object of this invention is to provide a machine cf this kindwhich can be easily and cheaply manufactured and which embodies -arelatively small number of moving partswhich can be constructed in sucha manner as notto get out of order.

A further object of this invention is to` provide a machine of this kindwhich is .sol Constructed that a pan of buns may be easily and quicklyinserted in the pressing portion ofthe machine, so that the machine maybe continuously operated and a new pan of buns inserted in the;for wardor pressing portion thereof while thepressing element is on its coatingcycle.

To the foregoing objects and others `Whicl'imay hereinafter appear, theinvention consists'ofthe novel construction, lcombination andarrangement cf parts as will be more specifically referred to andillustrated in the accompanying drawings, but it is to be understoodthat changes, variations and modifications may be resorted -to whichfall within the scope of the invention as claimed.

In the drawings:

Figure 1 is a detail side elevation `of agbun pressing machineconstructed according to an embodiment of this invention,

Figure 2 is a detail top plan ofthe machine,

Figure 3 is a detail end elevation Yofthe machine, and

Figure 4 is a fragmentary verticaltsection of the machine with thepressing elementinbun pressing position.

Referring to the drawings theA numeral I designates generally va framestructure including a plurality of uprightsorposts I Iwhichgareconnected together adjacent their lower portions aby horizontalend frame members I2 and horizontal side frame membersL I3. .Theuprights'ILare connected together adjacent the upper end Vpor` tionsthereof by end frame members I4 and horizontal side frame members I5.The framestructure I0 also includes a horizontally disposed table I6which is secured in any suitable mannergto ,the upper end ofthe. frameI0.

along the length of the plate 30. The plate is movably supported bymeans of a pair of rockable front levers 32 which are mounted on ahorizontally disposed shaft 33 xed beneath the table |6 and extendingthrough the side frame members |5. The upper side of the plate 30 hasmounted thereon a pair of spaced apart bearings 34 through which a frontpresser supporting shaft 35 rockably engages. The opposite end portionsof the shaft 35 are rockably secured through the upper end portions ofthe levers or arms 32. Nuts or fastening elements 36 engage the oppositeends of the shaft 35 so as to hold this shaft against endwise movementwith respect to the arms 32.

A second or rear pair of rockable arms or levers 31 are rockably mountedon a'horizontally disposed shaft 38 which is extended through the sideframe members I5. The upper side of the bun pressing member 29 hassecured thereto a rear pair of bearings 39 through which a rear The0pposite ends of the shaft 4|) are journalled through the upper endportions of the arms 31 and the shaft 49 is held against endwisemovement by means of nuts or fastening members' 4|.

The pairs of supporting arms or levers 32 and V31 are extended below theshafts 33 and 38 respectively, and have pivotally secured to the lowerends thereof lever tie bars 42. The tie bars 42 are disposed in ahorizontal position and at their forward ends are secured to the lowerends of the levers or arms 32 by fastening means 43. The tie bars 42 aresecured to the lower end portions of the levers or arms 31 by fasteningmeans 44. The rear end portions of the tie bars or rods 44 are bentdownwardly at an obtuse angle as at 45, and a transversely disposedshaft 46 is journalled inthe lower rear end portions of the obtuseextensions 45. The shaft is held against endwise movement with respectto the extensions 45 by fastening devices 41.

In order to provide a means whereby the levers or arms 32 and 31 may berocked forwardly and rearwardly, I have provided a power member 48 inthe form of an electric motor which is supported on a supporting framestructure 49. The shaft 5B of the motor 48has secured-thereto arelatively small pulley aboutV Which a belt 52 is trained. Acountershaft 53 is rotatably carried by the supporting frame 49 beingjournalled in bearings 54 carried by the frame 49.

` 4A relatively large pulley 55 is fixed to the countershaft 53, and thebelt 52 is trained about the pulley 55. A small pulley 56 is also fixedto the countershaft 53 rearwardly from the pulley and a belt or flexibledrive member 51 is trained about the small pulley 56. A second shaft 58is journalled in bearings 59 carried by the frame 48 and has xed theretoa large pulley 60. By means of the gear train hereinbefore described,the shaft 58 is adapted to turn at the desired slow speed. 'Ihe shaft 58adjacent the rear portion thereof has fixed thereto a worm 6|. The worm6| meshes with a worm gear 62 which is carried by a transverselydisposed shaft 63. The shaft 63 is journalled in a bearing 64 carried bythe frame 49 below the shaft 58.

A crank arm 65 is fixed at one end to the worm gear shaft 63 and theopposite end of the crank 65 is pivotally secured as at 66 to the frontend of'a pitman 61. The rear end of the pitman 61 is mounted on theshaft 46 as at 68, so that rotation of the crank 65 will effectoscillation or move- Y ment back and forth of the levers 32 and 31, andprovide for the movement of the pressingA member 29 from the flourreceptacle or coating member 22 to the pressing table l1, and then backto the coating table 22.

In the use and operation of this device the buns B are initially placedwithin the pan I8 in spaced apart relation and in spaced rows. The panI8 is then moved rearwardly on the table or support |1. The motor 48v isoperated in the usual manner, and when the bun pressing member 29 is inits rearmost position or coating cycle, the bun engaging members 3| willpress on the flour disposed in the flour chamber 28 thereby coating thelower sides of the pressing members 3|. The bun pressing member 29 isthen moved upwardly and forwardly and then downwardly to `the positionshown in Figure 4 wherein the bun engaging members 3| will contact thebuns B and compress these buns within the pan I8. The bun engagingmembers 3| may be either smooth or their lower facesmay be provided withsuitable indicia or other designs which are to'be impressed in the uppersides of the buns B. After the crank 35 moves the bun pressing member 29to the pressing position which is shown in Figure 4, the continuedrotation of the crank will then return the bun pressing member 29 totheiiour or coating receptacle 28 where the cycle will be repeated. Uponreturn of the pressing member 29 to a bun pressing position, a new panof buns is inserted on the table |1 between the guides I9 and to thelimit permitted by the stop flange or bead 2|.

The use of this machine will eliminate the necessity foi` hand pressingor compressing the buns after they have been placed in the pan, and willprovide for an even compressing of the buns which is not obtainablethrough a hand operation. Furthermore, with a machine of this kind thedough pieces which are of equal size are not only compressed to thedesired degree so that they are of equal height but in the compressingoperation the dough pieces will spread laterally to an even degree sothat they will be of equal diameter or size.
